These 45 series modules are the same as the original designs, and contain all of the original components.
1073 Chan nel Am pli fiers
These very popular sounding mic pre's are considered by many to capture the very essence of the Neve sound. In manufacture since the early 1970s, the Class A design offers 3 bands of EQ with one fixed high frequency and a high pass filter.
1084 Chan nel Am pli fiers
Based on the same technology as the 1073s, the 1084s again deliver the unique sound and quality of Neve. However, the 1084s offer additional features, including 3 switchable EQ bands with cut and boost, a high Q for presence and low pass/high pass filters.
High Pass Fil ter (re sis tor mod i fi ca tion)
Im por tant Note
The high pass filter in both the 1073 & 1084 modules is a passive design and as such must be correctly terminated to achieve a maximally flat response.
In order to achieve this there is a 5k1 resistor fitted inside the module on the back connector between pin E (0v) and pin K (fader send) see diagram below:
In situations where the fader connection is not used (most Neve 45 series consoles except BCM10's) then the resistor remains in place.
In situations where the fader connection is used (BCM10's and AMS Neve 1073/1084 racks) then the 5k1 resistor should be disconnected and replaced with a fader or potentiometer whose value is 4k7 / 5k ohms.
- All mod ules which leave the fac tory with ei ther a 3U or 5U rack unit will have the 5K1 re sis tor
re moved.
Failure to do so will result in incorrect levels and uneven frequency response.

The 1073s and 1084s are available as stand-alone modules, or in a choice of two housings.
The 3U rack houses two modules mounted horizontally in a 19” rack-mounting unit.
The 5U rack houses eight modules mounted vertically in a 19” rack-mounting unit.
Both have rear panels with XLRs for transformer balanced I/O.
The 3U rack rear panel has a fused, voltage selector IEC mains input connector. The 5U rack has a free standing AC supply with a fused, voltage selector IEC mains input connector and connects to the rack via a connector and a 1.5 meter cable.
Modules of any combination can be fitted into a rack unit.

The 3U rack has a fused, voltage selector IEC mains input connector.
The 5U rack has a free standing AC supply with a fused, voltage selector IEC mains input connector and connects to the rack via a connector and a 1.5 meter cable.
The mains switch on the rear panel of the 3U rack unit is non-illuminating.
The CH (chassis) and 0V are linked internally.
DC Power Sup ply In di ca tors (rack units)
The red LED on the front panel of both 3U and 5U rack units indicates +24V power healthy when illuminated.
The green LED on the front panel of both 3U and 5U rack units indicates +48V power healthy when illuminated.
Phan tom Power
Phantom power can be supplied to each module by pressing the phantom power switch on the front panel of the 3U or 5U rack. The LED in the switch will illuminate confirming that phantom power is supplied.
Out put Level Con trol
Each channel has an independent Output Level Control. The control is post-input, post-EQ and pre-output. This control can reduce the level at the output.
When the Output Control is fully clockwise the output gain is unity. The output is 20dB down with the control in the mid-position.
